2.3.1.Reserved Targets. At any time during the period between the Effective Date and the [***] anniversary of the Effective Date prior to Vertex’s exercise of the Additional Target Option, subject to Section 2.3.2, Vertex may designate a single Target as reserved for the Additional Target Option (the “Reserved Target”) by providing written notice to the Gatekeeper (the “Reserved Target Notice”), which Reserved Target Notice will identify the proposed Reserved Target. In such event, unless the applicable Target Availability Notice delivered by the Gatekeeper pursuant to Section 2.3.2 states that such proposed Reserved Target is an Unavailable Target, such proposed Reserved Target will automatically be designated as the Reserved Target as of the date the Gatekeeper identifies the Reserved Target in the Target Availability Notice provided to the Parties pursuant to Section 2.3.2 (such date, the “Reserved Target Designation Date”). [***]. Unless the applicable Target Availability Notice delivered by the Gatekeeper pursuant to Section 2.3.2 states that such proposed other Target is an Unavailable Target, such proposed other Target will automatically be designated as the Reserved Target, and the Target formerly designated as the Reserved Target will no longer be the Reserved Target; provided that the Reserved Target Designation Date shall remain the same and neither the Reserved Target Designation Date nor the Reserved Target Outside Date shall be modified in the event [***]. Notwithstanding anything to the contrary in this Agreement, if Vertex does not exercise its Additional Target Option to add the Reserved Target as an Additional Target prior to the Reserved Target Outside Date, such Reserved Target will no longer be a Reserved Target, provided that Vertex may still exercise the Additional Target Option for such former Reserved Target during the Additional Target Option Period, subject to the procedures set forth in Section 2.3.2 (for clarity, as long as such former Reserved Target does not become an Unavailable Target). If Vertex exercises the Additional Target Option to add Target(s) that are not the Reserved Target as the Additional Target, then the Reserved Target will cease to be a Reserved Target effective as of the exercise of the Additional Target Option.

2.3.2.Unavailable Targets. On or before the Effective Date, Company will have established an account (the “Gatekeeper Account”) with a Third Party mutually agreed to by the Parties (the “Gatekeeper”) for the purpose of depositing a list of Unavailable Targets, which Company will have deposited in the Gatekeeper Account on or before the Effective Date.

The Gatekeeper Agreement will provide that, if Vertex proposes to (a) exercise the Additional Target Option to designate an Additional Target or (b) designate a Reserved Target, then (i) Vertex shall provide to the Gatekeeper the Additional Target Option Exercise Notice or the Reserved Target Notice, as applicable, identifying the proposed Additional Target or the proposed Reserved Target, as applicable, (ii) the Gatekeeper shall notify Company within two Business Days that Vertex has indicated interest in an unspecified Additional Target or an unspecified Reserved Target, as applicable (without identifying the proposed Additional Target or Reserved Target, as applicable, to Company), (iii) within [***] after such notice, Company shall provide the Gatekeeper with an updated list of Unavailable Targets as of the date of the Additional Target Option Exercise Notice or the Reserved Target Notice, as applicable (which updated list shall remove any Target formerly identified as an Unavailable Target that no longer satisfies the definition of an Unavailable Target), and (iv) within [***] after the Gatekeeper’s receipt of Company’s updated list of Unavailable Targets, the Gatekeeper shall notify the Parties whether the proposed Additional Target or Reserved Target, as applicable, is an Unavailable Target (a “Target Availability Notice”). If the proposed Additional Target or Reserved Target, as applicable, is not an Unavailable Target, the Target Availability Notice will include the identity of such proposed Additional Target or Reserved Target, as applicable. Company will be solely responsible for all expenses relating to the Gatekeeper Account.

2.4.Rights to Antibodies. Company will use [***] to obtain rights to Antibodies directed against each Collaboration Target and having properties as specified in the Research Plan, either by license from a Third Party or through engaging a Subcontractor, each as identified in the Research Plan, to identify such Antibodies. Company and Vertex will confer and collaborate with respect to obtaining rights to such Antibodies, and the Parties shall mutually agree on whether to license or acquire such rights, and from which Third Party identified in the Research Plan. Following such agreement of the Parties, Company will use [***] to negotiate a license or subcontract with such Third Party (or, as applicable, a new statement of work under an existing agreement with such Third Party) and will provide Vertex with the right to review and approve any such contract between Company or its Affiliates and such Third Party (each such agreement, including any such statements of work, an “Antibody Agreement”). Company will not enter into or subsequently amend any Antibody Agreement without the prior written approval of Vertex, which approval may be conditioned, delayed or withheld in Vertex’s sole discretion. [***] shall be [***] responsible for any payment obligations arising under any Antibody Agreement approved by Vertex directly as a result of the Research of such Antibodies directed against a Collaboration Target by or on behalf of Company, Vertex or any of their respective Affiliates or Vertex’s Sublicensees; provided that, if any such payment obligations constitute milestone or royalty payments due under such Antibody Agreement, after application of all available reductions to and deductions from such payment obligations under the applicable Antibody Agreement, Company shall provide Vertex with a reasonably detailed invoice for such milestone and royalty payments made by Company within [***] of the end of each Calendar Quarter in which any such payments were made by Company, and Vertex shall pay the undisputed portion of such invoice within [***] of receipt thereof. The provision of Section 7.9 shall apply to such amounts paid or payable by Vertex, mutatis mutandis. In the event that Vertex does not approve an Antibody Agreement [***], Vertex may contract directly with the applicable Third Party to obtain rights to such Antibody, in which case, (a) [***] incurred in obtaining such Antibody (i.e., [***]) up to [***] per Antibody Agreement for up to [***] Antibody Agreements, provided that (i) if Company has already entered into one Antibody Agreement, [***]. Without limiting the provisions of Section 8.1.2, if Vertex exercises the Option with respect to a Development Candidate and pays the applicable Option Exercise Fee in accordance with this Agreement, Company hereby assigns and agrees assign to Vertex or its designee (x) if the rights to the applicable Antibody(ies) have been licensed by Company, the Antibody Agreement related to the applicable Antibody(ies) or (y) if the rights to the applicable Antibody(ies) are owned by Company, all intellectual property rights related to the applicable Antibody(ies), in each case, that are included in the applicable Development Candidate with respect to such exercised Option (to the extent not already assigned to Vertex pursuant to Section 8.1.2).

Subject to Section 2.4 , Company may engage Subcontractors to perform Research Activities or Follow-On Research (as applicable); provided that (a) the applicable provisions of each agreement between Company and a Subcontractor shall be consistent with the corresponding provisions of this Agreement, including Section 8.1, and shall include confidentiality provisions that are at least as restrictive as those described in ARTICLE 12; (b) Company shall include in each such contract an assignment provision that permits Company to assign such contract to Vertex after the applicable License Effective Date, to the extent such contract (i) [***], and (ii) either (x) [***] or (y) [***]; and (c) Company shall not engage any Subcontractor to conduct any such activities without Vertex’s prior written consent in each case, provided that Vertex’s approval of a Research Plan or a Follow-On Research Plan naming such Subcontractor and the relevant activities to be subcontracted shall be deemed to constitute Vertex’s consent to the engagement of such Subcontractor with respect to such activities. Subject to Section 2.4, Company will be responsible for the effective and timely management of, and payment, of its Subcontractors, at Company’s sole cost and expense, subject to Section 7.8. The engagement of any Subcontractor in compliance with this Section 2.6 shall not relieve Company of its obligations under this Agreement.

2.7.1.Records . Company shall maintain, and shall cause its Affiliates and Subcontractors to maintain, records of the Research Activities and Follow-On Research (as applicable) in sufficient detail and in good scientific manner appropriate for scientific, patent and regulatory purposes, which shall be complete and accurate in all material respects and shall fully and properly reflect all work done, data and developments made, and results achieved.

2.7.2.Progress Reports . During any period that Company is conducting Research Activities or Follow-On Research, Company shall furnish to the JAC (or, if the JAC has disbanded, directly to Vertex), within [***] after the end of each Calendar Quarter, an update on Company’s progress under the Research Plan for the applicable Collaboration Program or Follow-On Research Plan, as the case may be, with respect to the performance of the Research Activities or Follow-On Research (as applicable) during the relevant Calendar Quarter, including a summary of any results and data generated by Company under such Research Plan or Follow-On Research Plan and an overview of the resources, including an overview of FTEs, allocated to activities under such Research Plan or Follow-On Research Plan during the relevant Calendar Quarter. Company shall provide the JAC (or, if the JAC has disbanded, Vertex) with such other information with respect to the Collaboration Programs or Follow-On Research in Company’s Control as any member of the JAC (or Vertex) may reasonably request. All such updates and other information provided by Company shall be Company’s Confidential Information and shall be subject to the terms of ARTICLE 12, provided, however, that (a) any such updates and other information solely regarding a Development Candidate for which Vertex has exercised the Option shall, from and after the applicable License Effective Date, be Vertex’s Confidential Information and (b) any such updates or other information regarding both a Development Candidate for which Vertex has exercised the Option and one or more other Development Candidates for which Vertex has not exercised the Option shall, from and after the applicable License Effective Date, be the Confidential Information of both Parties.

3.1.1.Formation. Within [***] after the Effective Date, the Parties will establish a joint advisory committee (the “JAC”) to act as a forum to review, discuss and oversee activities under this Agreement and to address issues and share information relating to the Research Plan and, if applicable, any Follow-On Research Plan. The JAC will be comprised of [***] representatives from each Party, or such other equal number of representatives from each Party as the Parties may agree. Each Party’s representatives on the JAC shall be of the seniority and experience appropriate in light of the functions and responsibilities of the JAC. In addition, each Party may invite a reasonable number of additional subject matter experts or relevant personnel of such Party to participate in discussions and meetings of the JAC; provided that no such experts or personnel will have the authority to vote on any matters under consideration by the JAC. Each Party’s representatives on the JAC and all other individuals attending or participating in discussions and meetings of the JAC will be bound under written confidentiality and non-use obligations that are no less restrictive than the provisions of ARTICLE 12 with respect to information disclosed in such discussions or meetings. Each Party may replace its representatives on the JAC at any time upon written notice to the other Party (which notice may be given by email or in accordance with Section 13.5). The Company will designate the chairperson of the JAC from the Effective Date until the end of Calendar Year 2020, Vertex will designate the chairperson of the JAC from the start of Calendar Year 2021 until the end of Calendar Year 2021, and the JAC chairperson will alternate between the Parties annually thereafter. The chairperson of the JAC will be responsible for setting the agenda for meetings of the JAC with input from the other members of the JAC, and for conducting the meetings of the JAC. The JAC will conduct its responsibilities hereunder in good faith and with reasonable care and diligence.

3.1.2.Responsibilities. In addition to its overall responsibility to provide oversight and to facilitate information sharing between the Parties with respect to the Research Activities and, if applicable, the Follow-On Research, the JAC will:

(b)review and discuss all material Research Activities undertaken by or on behalf of Company under the Research Plan, including the exchange and review of data and information generated pursuant to the Research Plan;

(c)determine whether to designate as a Development Candidate for a Collaboration Program any ETB directed against the Collaboration Target with respect to such Collaboration Program that has not otherwise satisfied the applicable criteria for a Development Candidate set forth in the Research Plan;

(e)discuss Company’s progress toward preparation of each Option Exercise Data Package;

(f)oversee the transfer of Licensed Know-How to Vertex in accordance with Section 5.3;

(g)discuss and oversee any Follow-On Research that is mutually agreed by the Parties with respect to a Vertex Target; and

(h)perform such other duties as are specifically assigned to the JAC under this Agreement or as may be otherwise mutually agreed by the Parties from time to time.

(a)The JAC will meet in person or by teleconference at least [***] on such dates and at such times and places as agreed to by the members of the JAC; provided that at least [***] shall be in person unless the Parties agree otherwise. Each Party will be responsible for its own expenses relating to attendance at, or participation in, JAC meetings.

(b)The responsibility for preparing the minutes of the JAC’s meetings will alternate between the Alliance Managers on a meeting-by-meeting basis. The Alliance Manager responsible for the minutes will provide the other Alliance Manager and the members of the JAC with draft written minutes for the JAC’s approval within [***] after each meeting setting forth, among other things, a description, in reasonable detail, of the discussions at the meeting and a list of any actions, decisions or determinations approved by the JAC. Such minutes will be effective only after being approved by both Parties. If the minutes of any meeting of the JAC are not unanimously approved by the JAC within [***] after such meeting, then the Party objecting to the approval of such minutes will append a notice of objection with the specific details of the objection to the proposed minutes.

3.1.4.JAC Decision-Making. The JAC will use reasonable, good faith efforts to reach unanimous agreement with respect to all matters within the JAC’s authority, and no action or decision will be taken by the JAC without unanimous consent of the JAC’s members. If the JAC is not able to reach agreement with respect to a matter at a duly called meeting of the JAC, either Party may refer such matter to the Executive Officers of the Parties by delivering written notice to the other Party, and the Executive Officers will confer in good faith on the resolution of the issue for a [***] period (or such other period of time as mutually agreed by the Executive Officers) following receipt of such written notice. If such matter is not resolved by the Executive Officers within such [***] period, then (a) Company will have the final decision-making authority with respect to [***], (b) the Parties will decide by mutual agreement whether [***], (c) the Parties will determine by mutual agreement [***], (d) the Parties will decide by mutual agreement any [***], and (e) Vertex will have the final decision-making authority [***]; provided, however, that neither Party may exercise final decision-making authority if such decision would [***] without the other Party’s prior written consent. Notwithstanding any provision of this ARTICLE 3 to the contrary, the JAC will not have the authority to amend the terms or conditions of this Agreement, interpret this Agreement, or determine whether or not a Party has met its obligations under this Agreement or whether or not a breach of this Agreement has occurred.

3.1.5.Discontinuation of the JAC . The JAC will continue to exist until the first to occur of (a) the Parties mutually agreeing to terminate the JAC, (b) the completion or termination of the Research Plan (provided that Vertex may elect to reconstitute the JAC in the event of any Follow-On Research, and thereafter the JAC will continue to exist for the sole purpose of discussing and overseeing the Follow-On Research until the completion or termination of the Follow-On Research Plan), or (c) the expiration or termination of this Agreement for any reason.

3.2.IP Committee. Within [***] after the Effective Date, the Parties will form a committee (the “IP Committee ”), composed of an equal number of representatives from each Party having relevant expertise, to coordinate the Prosecution and Maintenance of Licensed Patents. The IP Committee will meet in person or by means of telephone or video conference at least [***] during the Term. Each Party may replace its representatives on the IP Committee at any time by providing notice in writing to the other Party. The IP Committee will have no decision-making authority, but will act as a discussion forum between the Parties. In addition, each Party may invite a reasonable number of additional subject matter experts or relevant personnel of such Party to participate in discussions and meetings of the IP Committee. Each Party’s representatives on the IP Committee and all other individuals attending or participating in discussions and

meetings of the IP Committee on behalf of a Party will be bound under written confidentiality and non-use obligations with respect to information disclosed at such meeting that are no less restrictive than the provision of ARTICLE 12.

3.3.Other Committees . The Parties may, by mutual agreement, form such other committees or working groups as may be necessary or desirable to facilitate activities under this Agreement.

3.4.1.Appointment. Each Party will appoint a representative of such Party to act as its alliance manager under this Agreement (each, an “Alliance Manager”). Each Party may replace its Alliance Manager at any time upon notice to the other Party. The initial Alliance Managers will be:

3.4.2.Specific Responsibilities. The Alliance Managers will attend all meetings of the JAC, but may not be members of the JAC. The Alliance Managers will serve as the primary contact point between the Parties for the purpose of providing each Party with information regarding the other Party’s activities pursuant to this Agreement and will have the following responsibilities:

(a)schedule meetings of the JAC and circulate draft written minutes as provided in Section 3.1.3(b);

(b)oversee and facilitate the flow of information and otherwise promote communication, coordination and collaboration between the Parties;

(c)provide a single point of communication for seeking consensus, both internally within the respective Party’s organization, and between the Parties regarding key strategy and planning issues; and

4.1.Options. On a Development Candidate-by-Development Candidate basis until the Option Deadline, Company hereby grants to Vertex an exclusive option to obtain the Exclusive License for the applicable Development Candidate and the corresponding Licensed ETBs and Licensed Products (each, an “Option”). For clarity, Vertex may exercise an Option with respect to more than one Development Candidate directed against a given Collaboration Target, and the failure to exercise an Option with respect to any given Development Candidate will not limit Vertex’s ability to exercise an Option with respect to any other Development Candidate.

4.1.1.Option Exercise Data Package. Within [***] after completion of the final study report for the last non-GLP NHP study conducted by Company with respect to a Development Candidate pursuant to the Research Plan, or otherwise upon Vertex’s earlier written request, Company will deliver to Vertex the Option Exercise Data Package for such Development Candidate (or, in the case of Vertex’s earlier request, Company will deliver all portions of the Option Exercise Data Package for such Development Candidate that are then available and in Company’s possession). If Vertex reasonably determines that any Option Exercise Data Package is incomplete or otherwise does not conform to the requirements of this Agreement, then, within [***] after Vertex’s receipt of such Option Exercise Data Package, Vertex may notify Company of the incomplete or non-conforming status of such Option Exercise Data Package, which notice shall specify the information required to be included in such Option Exercise Data Package which is incomplete or non-conforming (and, if the latter, how the information is non-conforming) (“Incomplete Data Package Notice”). Following Company’s receipt of an Incomplete Data Package Notice, Company will promptly deliver to Vertex the additional information specified in the Incomplete Data Package Notice as needed to complete such Option Exercise Data Package and, within [***] of receipt of such additional information, Vertex will provide Company a written acknowledgement that the Option Exercise Data Package is complete or will provide another Incomplete Data Package Notice. If Vertex does not provide either such acknowledgement or another Incomplete Data Package Notice within such [***] period, the Option Exercise Data Package will be deemed complete. Following Company’s delivery to Vertex of a complete Option Exercise Data Package, Vertex will have the right, prior to the Option Deadline, to reasonably request additional information relating to the applicable Development Candidate, and Company will respond to any such reasonable request promptly with any such additional information that is in its Control; provided that Company shall in no event be required to conduct any new or additional Research or other activities to generate any such additional information.

4.1.2.Option Exercise. Vertex may exercise its Options for one or more Development Candidates arising under a Collaboration Program by providing written notice to Company (the “Option Exercise Notice”) at any time between the Effective Date and the date that is [***] after Company delivers to Vertex a complete Option Exercise Data Package for the final Development Candidate for such Collaboration Program as determined by the JAC (the “Option Deadline”). For clarity, the Option Deadline for the Development Candidates under each Collaboration Program will be calculated based on the date that Company delivers a complete Option Exercise Data Package for such final Development Candidate, and will not be calculated based on the date, if applicable, that Company delivers an Option Exercise Data Package for such final Development Candidate that is incomplete or otherwise does not conform to the requirements of this Agreement as evidenced by an Incomplete Data Package Notice. The Option Exercise Notice will specify the Development Candidate(s) with respect to which Vertex intends to exercise its Options. If Vertex delivers an Option Exercise Notice to Company with respect to one or more Development Candidates arising under a Collaboration Program prior to the Option Deadline, then Vertex will pay Company the Option Exercise Fee in accordance with Section 7.3 with respect to each such Development Candidate. On the License Effective Date for any such Development Candidate, (a) the applicable Collaboration Target will automatically become a “Vertex Target,” and (b) Company will automatically grant to Vertex the Exclusive License for such Development Candidate and the corresponding Licensed ETBs and Licensed Products. On a Development

Candidate-by-Development Candidate basis, if Vertex fails to provide an Option Exercise Notice in accordance with this Section 4.1.2 with respect to a Development Candidate prior to the Option Deadline, then the Option for such Development Candidate will expire and be of no further force or effect and, for clarity: such Development Candidate shall not be a Licensed ETB; any Agreement Know-How pertaining solely to such Development Candidate shall not be deemed Product Agreement Know-How; and Vertex shall have no rights in or to such Development Candidate.

4.2.1.HSR Notice. If Vertex determines in good faith upon advice of counsel that an HSR Filing is required to be made under the HSR Act as a result of Vertex’s exercise of an Option and notifies Company of such determination in connection with Vertex’s delivery of the applicable Option Exercise Notice, then (i) the Parties will file an HSR Filing in accordance with Section 4.2.2, and (ii) Vertex’s election to exercise the applicable Option will not be effective (and Vertex will not be obligated to pay the applicable Option Exercise Fee) until the HSR Clearance Date, if any.

4.2.2.HSR Filing. If Vertex notifies Company pursuant to Section 4.2.1 that an HSR Filing is required for Vertex to exercise an Option, then each of Vertex and Company will, within [***] after such notice from Vertex (or such later time as may be agreed to in writing by the Parties), file with the U.S. Federal Trade Commission (“FTC”) and the Antitrust Division of the U.S. Department of Justice (“DOJ”) any HSR Filing required with respect to the transactions contemplated hereby. Each of the Parties agrees to cooperate in the antitrust clearance process, including by furnishing to the other Party such necessary information and reasonable assistance as the other Party may reasonably request in connection with its preparation of any filing or submission that is necessary under the HSR Act and other antitrust requirements, and to furnish promptly with the FTC, DOJ, and any other antitrust authority, any information requested by them in connection with such filings. Each Party shall furnish copies (subject to reasonable redactions for privilege or confidentiality concerns) of, and shall otherwise keep the other Party apprised of the status of any material communications with, and any inquiries or requests for additional information from, the FTC, DOJ and any other antitrust authority, and shall comply promptly with any such inquiry or request. Each Party shall give the other Party the opportunity to review in advance, and shall consider in good faith the other Party’s reasonable comments in connection with, any proposed filing or communication with the FTC, DOJ or any other antitrust authority. Each Party shall consult with the other Party, to the extent practicable, in advance of participating in any substantive meeting or discussion with the FTC, the DOJ or any other antitrust authority with respect to any filings, investigation or inquiry and, to the extent permitted by such antitrust authority, give the other Party to the opportunity to attend and participate therein. Each Party will be responsible for its own costs and expenses (other than filing fees, which Vertex will pay) associated with any HSR Filing.

4.2.3.HSR Clearance. In furtherance of obtaining clearance for an HSR Filing filed pursuant to this Section 4.2, Company and Vertex will use their respective Commercially Reasonable Efforts (subject to this Section 4.2.3) to resolve as promptly as practicable any objections that may be asserted with respect to this Agreement or the transactions contemplated by this Agreement under any antitrust, competition or trade regulatory law. In connection with such clearance for an HSR Filing from the FTC, the DOJ or any other Governmental Authority, neither Party, nor its Affiliates will be required to (i) sell, divest (including through license or a reversion of licensed or assigned rights), hold separate, transfer or dispose of any assets, operations, rights, product lines, businesses or interest therein of such Party or any of its Affiliates (or consent to any of the foregoing actions); or (ii) litigate or otherwise formally oppose any determination (whether judicial or administrative in nature) by a Governmental Authority seeking to impose any of the restrictions referenced in clause (i) above.

5.1.1.Exclusive License. On a Development Candidate-by-Development Candidate basis, effective upon the License Effective Date for the applicable Development Candidate, Company hereby grants to Vertex and its Affiliates an exclusive, royalty-bearing license, including the right to grant and authorize Sublicenses in accordance with Section 5.1.2, under Company’s and its Affiliates’ interests in the Licensed Technology, to Research, Develop, Manufacture, have Manufactured, Commercialize, use, keep, and otherwise exploit such Development Candidate and all corresponding Licensed ETBs and Licensed Products in the Field in the Territory (each, an “Exclusive License ”).

5.1.2.Sublicensing. Vertex and its Affiliates may grant Sublicenses of any Exclusive License through multiple tiers of Sublicenses to one or more Sublicensees. Each such Sublicense will be consistent with the terms of this Agreement and will require the Sublicensee to comply with the terms of this Agreement that are applicable to such Sublicense, including obligations of confidentiality and non-use at least as stringent as those set forth in ARTICLE 12, the reporting obligations set forth under Section 7.5.3 and Section 7.6.7, the record keeping and audit requirements set forth under Section 7.11, and the intellectual property assignment provisions set forth in Section 8.1.2. Vertex will, as soon as reasonably practicable (and in any event within [***] thereafter), provide Company with a copy of each executed Sublicense with a Third Party Sublicensee (which copy may be redacted to remove provisions which are not necessary to monitor compliance with this Section 5.1.2); provided that Vertex shall have no obligation to provide Company with any copy of any Subcontractor agreement. Notwithstanding any Sublicense, Vertex will not be relieved of any of its obligations under this Agreement and will remain primarily liable to Company for the performance of all of Vertex’s obligations under this Agreement and for the acts or omissions of or breach of this Agreement by any Sublicensee.

5.1.3.Retained Rights. Other than those expressly set forth in this Agreement, no rights or licenses are granted to Vertex by Company hereunder. Company retains all right, title and interest in and to the Licensed Technology, subject to any Exclusive License granted by Company to Vertex pursuant to Section 5.1.1, and all rights not expressly granted by Company to Vertex hereunder are reserved and retained by Company. Notwithstanding any Exclusive License granted to Vertex pursuant to Section 5.1.1 , Company will retain rights under the Licensed Technology to the extent necessary to perform its obligations under this Agreement, including to perform the Research Activities and any Follow-On Research as may be agreed by the Parties.

5.2.1.Research License . Vertex hereby grants to Company and its Affiliates a non-exclusive, fully paid-up, non-transferable (except as provided in Section 13.1), royalty-free license in the Territory, with no right to grant sublicenses except to Subcontractors engaged in accordance with Section 2.6 , under the Vertex Technology, solely to perform the Research Activities and, if applicable, the Follow-On Research. Such license shall terminate automatically upon completion of such Research Activities or, if applicable, such Follow-On Research.

5.2.2.Antibody Agreement Technology License. On a Terminated Target-by-Terminated Target basis for any Collaboration Target that becomes a Terminated Target, Vertex shall grant and hereby grants to Company and its Affiliates, effective as of the expiration of the Option Deadline for the final Development Candidate directed against such Terminated Target, an exclusive, royalty-free, irrevocable, perpetual, worldwide license, including the right to grant and authorize sublicenses through multiple tiers, under the Antibody Agreement Technology for such Terminated Target, to [***], subject to the terms and conditions of this Agreement and any relevant Third Party agreements with respect to such Antibody Agreement Technology.

5.3.1.Licensed Know-How Transfer. On a Development Candidate-by-Development Candidate basis, following the License Effective Date with respect to a Development Candidate, upon Vertex’s request, which request will occur within [***] following the License Effective Date with respect to such Development Candidate, Company will promptly transfer to Vertex or its designated Affiliate a copy of all Licensed Know-How related to such Development Candidate (or the corresponding Licensed ETBs or Licensed Products) in its Control as of such License Effective Date, including any documentation (whether held in paper or electronic format) or similar removable media (including emails, documents, spreadsheets, copies of standard operating procedures or technical specifications), and will complete such transfer no later than [***] following Vertex’s request. In addition, on a Development Candidate-by-Development Candidate basis, to the extent Company has performed Follow-On Research with respect to such Development Candidate, Company will promptly, following completion of such Follow-On Research, transfer to Vertex or its designated Affiliate a copy of all Licensed Know-How related to such Development Candidate (or the corresponding Licensed ETBs or Licensed Products) generated under the Follow-On Research in its possession as of such completion date, including any documentation (whether held in paper or electronic format) or similar removable media (including e-mails, documents, spreadsheets, copies of standard operating procedures or technical specifications), and will complete such transfer no later than [***] following completion of such Follow-On Research, in each case, to the extent not previously provided pursuant to this Section 5.3.1.

5.3.2.Additional Transfers. On a Development Candidate-by-Development Candidate basis, following the License Effective Date with respect to a Development Candidate and during [***], no more than once every [***] during the first [***] after the License Effective Date [***], Vertex may inform Company in writing of its [***] and Manufacturing activities with respect to Licensed Products. Upon such information being provided by Vertex, or otherwise upon a general request by Vertex, in either case no more than once every [***] during the first [***] after the License Effective Date [***], Company will, within [***] after receipt of such information or request, notify Vertex [***] that has come into Company’s Control, including any [***] generated during any applicable Follow-On Research, in each case that, based upon such information provided by Vertex (if any), it reasonably determines would be necessary [***] to Vertex’s [***] and Manufacturing activities with respect to Licensed Products, in each case, to the extent not previously provided by Company. Upon receipt of such notice from Company, Vertex may request a copy of [***] from Company, and Company will promptly transfer to Vertex or its designated Affiliate a copy of [***] in Company’s Control, including any documentation (whether held in paper or electronic format) or similar removable media (including emails, documents, spreadsheets, copies of standard operating procedures or technical specifications), and will complete such transfer no later than [***] following Vertex’s request. Additionally, if Vertex becomes aware of any [***] that comes into Company’s Control, in each case to the extent not previously provided by Company, then Vertex may request a copy of such [***] from Company. Company will, promptly following such request [***] necessary [***] for Vertex’s [***] or Manufacturing activities with respect to the Licensed Products, transfer to Vertex or its designated Affiliate a copy of such [***] in Company’s Control, including any documentation (whether held in paper or electronic format) or similar removable media (including emails, documents, spreadsheets, copies of standard operating procedures or technical specifications), and will complete such transfer no later than [***] following Vertex’s request. Notwithstanding the foregoing, with respect to any such [***] relating to the Manufacture of Licensed ETBs or Licensed Products, the obligations set forth in this Section 5.3.2 shall apply only to the extent that Vertex informs Company of the then-current Manufacturing process used by or on behalf of Vertex, its Affiliates or its Sublicensees for any such Licensed ETBs or Licensed Products and that such [***] constitutes an improvement, modification or enhancement to such Manufacturing process.

5.3.3.No Transfers of Other Know-How. For clarity, Company will not have any obligation under Section 5.3.1 or Section 5.3.2 to transfer any Know-How to the extent such Know-How is not within the scope of the Licensed Know-How.

5.3.4.Assistance by Company Personnel. To assist with the transfer of Licensed Know-How under this Section 5.3 and Vertex’s exploitation thereof in accordance with the terms of this Agreement, Company will make its personnel reasonably available to Vertex during normal business hours to transfer such Licensed Know-How to Vertex and respond to Vertex’s reasonable inquiries with respect thereto. Company will be responsible for [***] and Vertex will reimburse Company for (a) [***] and (b) [***], in each case within [***] after receiving Company’s invoice therefor.

5.3.5.Third Party Vendors or Subcontractors. At Vertex’s reasonable request following the License Effective Date with respect to a given Development Candidate, Company will use Commercially Reasonable Efforts to facilitate the establishment of a business relationship between Vertex and any Subcontractor that Company has engaged in the Research Activities or in the Manufacture of such Development Candidate (or the corresponding Licensed ETBs or Licensed Products), including by facilitating introductions with such Subcontractors, and will use Commercially Reasonable Efforts to assign to Vertex any agreements with any such Subcontractor that are solely related to such Development Candidate (or the corresponding Licensed ETBs or Licensed Products).

5.4.No Implied Licenses. Except as expressly provided in this Agreement, no Party will be deemed by estoppel, implication or otherwise to have granted the other Party any license or other right with respect to any intellectual property.

5.5.Bankruptcy. All rights and licenses granted under or pursuant to this Agreement by a Party to the other are and will be deemed to be, for purposes of Section 365(n) of the Bankruptcy Code, licenses of rights to “intellectual property” as defined under Section 101 of the Bankruptcy Code. The Parties agree that the Parties will retain and may fully exercise all of their rights and elections under the Bankruptcy Code and any foreign equivalent thereto. The Parties further agree that if (x) a bankruptcy proceeding by or against a Party (the “Bankrupt Party ”) is commenced under the Bankruptcy Code, (y) this Agreement is rejected as provided in the Bankruptcy Code, and (z) the other Party (the “Non-Bankrupt Party ”) elects to retain its rights hereunder as provided in Section 365(n) of the Bankruptcy Code, the Non-Bankrupt Party will be entitled to a complete duplicate of, and complete access to (as the Non-Bankrupt Party deems appropriate), all such intellectual property and all embodiments of such intellectual property. Upon such election by the Non-Bankrupt Party, such intellectual property and all embodiments of such intellectual property will be promptly delivered to the Non-Bankrupt Party. The Bankrupt Party (in any capacity, including debtor-in-possession) and its successors and assigns (including any trustee) agrees not to interfere with the exercise by the Non-Bankrupt Party of its rights and licenses to such intellectual property and such embodiments of intellectual property in accordance with this Agreement, and agrees to assist the Non-Bankrupt Party and its Affiliates in obtaining such intellectual property and such embodiments of intellectual property in the control of Third Parties. The foregoing provisions are without prejudice to any rights the Non-Bankrupt Party may have arising under the Bankruptcy Code or other Applicable Law.

5.7.Right of First Negotiation. If, on a Terminated Target-by-Terminated Target basis, within [***] following the expiration of the Option Deadline for the final Development Candidate directed against such Terminated Target, [***] will provide written notice (the “Terminated Target Notice”) to [***] of the general nature of the proposed transaction. The Terminated Target Notice will include information similar in nature and scope, taking into account the applicable stage of research or development of such product, to the information that would be required to be included in [***] for such Terminated Target in the form and to the extent that any such information is then available (and in [***]) for such [***] (including [***], if applicable), and [***] will have an exclusive right of first negotiation to acquire or obtain an exclusive license to such [***]. [***] will have [***] after receipt of any Terminated Target Notice from [***] to provide [***] notice that [***] desires to exercise such exclusive right of first negotiation with respect to such [***] (“Terminated Target Exercise Notice”). If [***] provides a timely Terminated Target Exercise Notice, then the Parties will promptly commence exclusive good faith negotiations regarding the terms of an agreement providing for such acquisition or the grant of such exclusive license for a period of up to [***] unless extended by mutual written agreement of the Parties, during which period [***] will not engage in any discussions or negotiations with or permit diligence access to any Third Party regarding the acquisition or license of such [***]. In the event that [***] does not provide a timely Terminated Target Exercise Notice, or the Parties fail to reach agreement within such [***] period (or such longer period as the Parties may mutually agree in writing), then [***] may enter into an agreement with any of its Affiliates or a Third Party with respect to the acquisition or license of such [***].

6.1.1.Generally . Vertex will have sole and exclusive control, at its sole cost and expense, over all matters relating to the Development of Licensed ETBs and Licensed Products in the Field in the Territory.

6.1.2.Development Plan. On a Vertex Target-by-Vertex Target basis, within [***] after the License Effective Date with respect to any Development Candidate directed against the applicable Vertex Target, Vertex will provide the JAC, or the Company if the JAC has disbanded, with a high-level Development plan outlining key aspects of the Development of Licensed ETBs and Licensed Products directed against such Vertex Target for the ensuing [***] period (the “Development Plan”), for informational purposes only. After the initial Development Plan has been provided to Company, Vertex will update such Development Plan no less than [***] for so long as activities are taking place under such Development Plan and provide such updates to Company for informational purposes only. For the avoidance of doubt, Vertex may, in satisfaction of its obligations hereunder, undertake activities other than, or in lieu of, those set forth in the Development Plan and in that case, Vertex will provide updates to Company of such activities in accordance with Section 6.1.3.

6.1.3.Reporting. During the Term until [***], no later than[***], Vertex will provide Company with a high-level report regarding the status of Vertex’s Development of Licensed ETBs and Licensed Products directed against such Vertex Target and the results of such Development.

6.2.1.Responsibilities . Vertex will have the sole and exclusive right, at its sole cost and expense, to (a) prepare, file and maintain Regulatory Filings, each in its own name (including applications for Marketing Approval and Price Approval) for all Licensed Products in the Field in the Territory, and (b) communicate with Regulatory Authorities with respect to the Licensed Products in the Field in the Territory, both prior to and following Marketing Approval and Price Approval, including all communications and decisions with respect to (i) labeling of Licensed Products, and (ii) [***], in each case, either by itself or with or through one or more Affiliates or Third Parties.

7.5.1.Development Milestones. On a Vertex Target-by-Vertex Target basis, Vertex will pay to Company the milestone payments set forth in this Section 7.5.1 (each a “Development Milestone Payment ”) in accordance with the procedure set forth in Section 7.5.3 upon the first achievement of the relevant milestone event (each a “Development Milestone Event ”) with respect to a Licensed Product of Vertex or any of its Affiliates or Sublicensees directed against such Vertex Target. Each Development Milestone Payment will be payable by Vertex only once with respect to each Vertex Target regardless of how many Licensed Products directed against such Vertex Target achieve the relevant Development Milestone Event. If any Development Milestone Event is achieved without the achievement of any earlier listed Milestone Event applicable to the same jurisdiction (or not specific to a jurisdiction), then Vertex will pay to Company the Development Milestone Payment applicable to such earlier Development Milestone Event at the same time as Vertex pays the applicable Development Milestone Payment in accordance with the procedure set forth in Section 7.5.3 due upon achievement of such Development Milestone Event. For example, if Development Milestone Event number 3 is achieved and Vertex has not previously made the Development Milestone Payment for Development Milestone Event number 2, Vertex will pay both the Development Milestone Payments for Development Milestone Event number 2 and Development Milestone Event number 3 at the same time (but, if Development Milestone Event number 6 is achieved and Vertex has not previously made the Development Milestone Payment for Development Milestone Event number 5, the achievement of Development Milestone Event number 6 will not give rise to any obligation of Vertex to make the Development Milestone Payment for Development Milestone Event number 5 (however, the Development Milestone Payment for Development Milestone Event number 5 will become payable upon achievement, if any, of Development Milestone Event number 5)). Additionally, if the [***] occurs, and Development Milestone Event number 2 has not yet been achieved with respect to the applicable Vertex Target at the time of such dosing, then Vertex will pay the Development Milestone Payment for Development Milestone Event number 2 for such Vertex Target in accordance with the procedure set forth in Section 7.5.3 upon[***]t.

7.5.2.Sales Milestones. On a Vertex Target-by-Vertex Target basis, Vertex will pay Company the milestone payments set forth in this Section 7.5.2 (each a “Sales Milestone Payment”, and, together with the Development Milestone Payments, the “Milestone Payments ”) in accordance with the procedure set forth in Section 7.5.3 upon the first achievement of the relevant [***] threshold (each, a “Sales Milestone Event”, and, together with the Development Milestone Events, the “Milestone Events ”) with respect to all Licensed Products of Vertex and its Affiliates and Sublicensees directed against such Vertex Target. Each Sales Milestone Payment will be payable by Vertex only once with respect to each Vertex Target regardless of how many times the Licensed Products directed against such Vertex Target achieve the relevant Sales Milestone Event.

7.5.3.Notice; Payment. Each Milestone Payment will be earned upon achievement of the corresponding Milestone Event, and Vertex will provide Company with written notice upon the achievement of each Milestone Event, such written notice to be provided (a) with respect to any Development Milestone Event, within [***] after such achievement, and (b) with respect to any Sales Milestone Event, on or prior to the date of delivery of the royalty report under Section 7.6.7 for the [***] in which such Sales Milestone Event is achieved. Following receipt of such written notice, Company will promptly invoice Vertex for the applicable Milestone Payment, and Vertex will pay such Milestone Payment to Company within [***] after receipt of such invoice. The Sales Milestone Payments are additive, such that if, with respect to a Vertex Target, more than one Sales Milestone Event is achieved for the first time with respect to such Vertex Target in the same Calendar Year, then each corresponding Sales Milestone Payment for such event will be payable in accordance with this Section 7.5.3.

7.6.1.Royalty Rates. Subject to the remainder of this Section 7.6 , Vertex will pay Company royalties on a Vertex Target-by-Vertex Target basis based on the aggregate Net Sales of all Licensed Products directed against such Vertex Target sold by Vertex or any of its Affiliates or Sublicensees in the Field in the Territory during a Calendar Year during the applicable Royalty Term at the rates set forth in the table below. The obligation to pay royalties will be imposed only once with respect to the same unit of a Licensed Product.

The applicable royalty rate set forth in the table above will apply only to that portion of the Calendar Year Net Sales of the Licensed Products directed against a given Vertex Target during a given Calendar Year that falls within the indicated range. By way of example and without limitation of this Section 7.6.1 , if Calendar Year Net Sales of the Licensed Products directed against a given Vertex Target by Vertex, its Affiliates and its Sublicensees were $[***] for a given Calendar Year, then the royalties payable with respect to such Calendar Year Net Sales for such Licensed Products for such Calendar Year, subject to adjustment as set forth in this Section 7.6, would be: [***].

7.6.2.Royalty Term. Vertex will pay royalties to Company under this Section 7.6 on a Licensed Product-by-Licensed Product and a country-by-country basis during the Royalty Term for such Licensed Product in such country. Upon the expiration of the Royalty Term for a given Licensed Product in a given country, the Exclusive License granted to Vertex under Section 5.1 will become fully-paid, perpetual, irrevocable and royalty-free with respect to such Licensed Product in such country.

7.6.3.Reduction for Lack of Patent Coverage and Regulatory Exclusivity. Subject to Section 7.6.6, if, during any [***] within the applicable Royalty Term for a Licensed Product in a country, (a) no Valid Claim of any Licensed Patent exists that Covers such Licensed Product or the method of use of manufacture of such Licensed Product in such country, and (b) Regulatory Exclusivity, if any, has expired in such country with respect to such Licensed Product (the “Reduction Circumstances”), then, commencing the [***], Net Sales of such Licensed

Product in such country will be reduced by [***]% for purposes of calculating the royalty owed under Section 7.6.1; provided that, if either one of the Reduction Circumstances no longer exists with respect to such Licensed Product in such country during the Royalty Term for such Licensed Product in such country (e.g., if such Licensed Product or its method of use or manufacture subsequently becomes Covered by a Valid Claim of any Licensed Patent in such country during the Royalty Term for such Licensed Product in such country), then the Net Sales with respect to such Licensed Product in such country will no longer be subject to any reduction during any [***] in which either of the Reduction Circumstances no longer exists.

7.6.4.Reduction for Competition. Subject to Section 7.6.6 , if during any [***] during the Royalty Term for a Licensed Product in a given country, the aggregate number of units of Competitive Products with respect to such Licensed Product sold during such [***] in such country exceeds [***]% of the aggregate units of the sum of all such Competitive Products and such Licensed Product sold in such [***] in such country (as determined by data obtained from a mutually agreed upon Third Party source), then Net Sales of such Licensed Product in such country in such [***] (after any applicable reduction pursuant to Section 7.6.3) will be reduced by [***]% for purposes of calculating the royalty owed under Section 7.6.1. For clarity, the reduction under this Section 7.6.4 shall only apply in the [***], if any, in which the aggregate number of units of Competitive Products with respect to a Licensed Product sold during the [***] in a country exceeds [***]% of the aggregate units of the sum of all such Competitive Products and such Licensed Product sold in such [***] in such country.

7.6.5.Third Party Licenses. Subject to Section 7.6.6, Vertex may deduct from the royalties payable to Company under this Section 7.6 with respect to a Licensed Product for a [***] [***]% of any Blocking Third Party Intellectual Property Costs actually paid by Vertex to the extent applicable to such Licensed Product during or prior to such [***]; provided, however, that in no event will the royalties that would otherwise be payable to Company with respect to Net Sales of Licensed Products pursuant to Section 7.6.1 (after any applicable reduction to such Net Sales pursuant to Section 7.6.3 and Section 7.6.4) be reduced by more than [***]% in any given [***] as a result of any deduction under this Section 7.6.5; and provided further, that Vertex will be entitled to carry forward to subsequent [***] any amounts with respect to which Vertex would have been entitled to make a deduction pursuant to this Section 7.6.5 but is unable to take such deduction pursuant to the first proviso in this Section 7.6.5.

7.6.6.Cumulative Reductions Floor. Notwithstanding anything to the contrary herein, in no event shall the cumulative effect of the adjustments in Section 7.6.3, Section 7.6.4 and Section 7.6.5 in any given [***] reduce the royalties payable to Company pursuant to Section 7.6.1 to less than [***]% of the amounts that otherwise would have been payable pursuant to Section 7.6.1 (without taking into consideration any such adjustments) in such [***].

7.6.7.Royalty Reports. On a Vertex Target-by-Vertex Target basis following the First Commercial Sale of a Licensed Product directed against a Vertex Target and continuing until the expiration of all Royalty Terms for Licensed Products directed against such Vertex Target, within [***] after the end of each [***], Vertex will deliver a report to Company specifying: (a) Net Sales of the Licensed Products directed against such Vertex Target by Vertex, its Affiliates and its Sublicensees in the relevant [***], (b) to the extent such Net Sales include sales not denoted in U.S. Dollars, a summary of the then-current exchange rate methodology used by Vertex, (c) royalties payable on such Net Sales, (d) the withholding taxes, if any, required by law to be deducted in respect of such royalties, (e) the amount and description of any reduction in royalties due to Blocking Third Party Intellectual Property Costs in the relevant [***], and (f) the date of the First Commercial Sale of each Licensed Product in each country in the Territory that has occurred during the corresponding [***]. All royalty payments due under Section 7.6.1 for each [***] will be due and payable within [***] after the end of each [***].

7.7.1.Proposed New Company Agreements . Company may, during the Term, enter into one or more agreements to acquire or in-license rights to additional intellectual property that, if solely owned by Company, without any encumbrance or restriction on licensing, would constitute Company Background Technology. Any such agreement that [***] will be considered to be a “Proposed New Company Agreement”. Notwithstanding the foregoing, the following shall not be considered a Proposed New Company Agreement: (i) an [***], or (ii) [***] (each, a “New Platform Agreement”). For clarity, (x) the terms of this Section 7.7 shall not apply to any Antibody Agreement and (y) the terms of Section 7.7.1(a) shall not apply to (A) any New Platform Agreement or (B) [***] (y), an “Other Company License Agreement”); provided that (I) subject to Section 7.7.4, the intellectual property in-licensed under any Other Company License Agreement, to the extent it constitutes Company Background Technology, shall be included in the license grant to Vertex hereunder, (II) [***], and (III) any Other Company License Agreement that includes intellectual property [***].

(a)If Company [***] with any Third Party (a “Grantor”) regarding a Proposed New Company Agreement, [***]. Company shall provide Vertex with [***].

(b)Any Proposed New Company Agreement shall be licensable or sublicensable (as the case may be) to Vertex under this Agreement. Company shall use reasonable, good faith efforts to [***].

7.7.2.New Company Agreements. [***] following execution of a Proposed New Company Agreement, Company shall provide to Vertex [***] shall constitute notice by Company that Company proposes to make such Proposed New Company Agreement subject to Section 7.7.3 if Vertex elects to have such Proposed New Company Agreement become a New Company Agreement in accordance with this Section 7.7.2. Company and Vertex will discuss in good faith to determine whether Vertex will take a license or sublicense (as the case may be) under all or a portion of the intellectual property rights that are the subject of such Proposed New Company Agreement, and Vertex will provide Company with written notice of its decision with

respect thereto. Following such notice, subject to the terms of such Proposed New Company Agreement that are applicable to a Licensee thereunder, such intellectual property rights shall automatically be deemed included in the Company Background Technology (any such Proposed New Company Agreement with respect to such intellectual property rights that are included in the Company Background Technology pursuant to this sentence, a “New Company Agreement”). For clarity, any intellectual property rights in-licensed or acquired by Company pursuant to a Proposed New Company Agreement that is not a New Company Agreement (i.e., under which Vertex does not agree to take a license or sublicense) shall not be included in Company Background Technology. Additionally, if Company later [***]; provided that, if Company does not propose to make such executed agreement subject to Section 7.7.3 (any such agreement, a “Later Company License Agreement), then, (i) subject to Section 7.7.4, the intellectual property in-licensed under any Later Company License Agreement, to the extent it constitutes Company Background Technology, shall be included in the license grant to Vertex hereunder and (ii) if a Later Company License Agreement imposes obligations applicable to Vertex as a sublicensee thereunder, then, subject to Company’s obligations of confidentiality to Third Parties, if any, Company shall provide to Vertex [***].

7.10.Withholding Tax. Where any sum due to be paid to Company hereunder is subject to any withholding or similar tax, Vertex will pay such withholding or similar tax to the appropriate Governmental Authority and deduct the amount paid from the amount then due to Company.

The Audited Party may require the accounting firm to sign a customary non-disclosure agreement before providing the accounting firm access to its facilities or records. Upon completion of the audit, the accounting firm will provide both Parties a written report disclosing whether the reports submitted by Vertex or the[***] submitted by Company, as applicable, are correct or incorrect and the specific details concerning any discrepancies. No other information will be provided to the Auditing Party. If the report or information submitted by the Audited Party results in an underpayment or overpayment, (a) the Party owing an underpaid amount will promptly pay the amount of such underpayment to the other Party, and (b) any such overpayment shall be creditable against future payments to the other Party hereunder.

8.3.Defense of Claims Brought by Third Parties. If any Third Party brings a claim or otherwise asserts that any ETB directed against a Collaboration Target, any Development Candidate, any Licensed ETB or any Licensed Product infringes such Third Party’s Patent or misappropriates such Third Party’s Know-How (each, a “Third Party Infringement Claim ”), the Party first having notice of the claim or assertion will promptly notify the other Party in writing. Prior to the applicable License Effective Date, Company will have the sole right to undertake and control the defense or settlement of any Third Party Infringement Claim using counsel of its choice, at its cost and expense and, following the applicable License Effective Date, Vertex will have the sole right to undertake and control the defense or settlement of any Third Party Infringement Claim using counsel of its choice, at its cost and expense (such Party having the right to control such defense, the “Defending Party”). If the Party not having the right to control such defense in accordance with the preceding sentence (the “Non-Defending Party ”) is named as a defendant in such suit, the Non-Defending Party will have the right to participate in such defense and settlement with its own counsel, at its cost. The Defending Party will not enter into any settlement of any Third Party Infringement Claim that is instituted or threatened to be instituted against the Non-Defending Party without the Non-Defending Party’s prior written consent, which will not be unreasonably withheld, conditioned or delayed; except that, such consent will not be required if such settlement includes a release of all liability in favor of the Non-Defending Party or an assumption of any unreleased liability by the Defending Party. As requested by the Defending Party, the Non-Defending Party will provide reasonable cooperation and assistance to the Defending Party in connection with the Defending Party’s control of the defense or settlement of a Third Party Infringement Claim.

The Defending Party will reimburse the Non-Defending Party for the Out-of-Pocket Costs incurred by the Non-Defending Party in providing such assistance and cooperation; except that the Defending Party will have no obligation to reimburse the Non-Defending Party for any costs or expenses incurred if the Non-Defending Party exercises its right to participate in the defense and settlement of a Third Party Infringement Claim with its own counsel. The Defending Party will keep the Non-Defending Party reasonably informed of the progress of any Third Party Infringement Claim. Notwithstanding anything to the contrary in this Section 8.3, in the event of any Third Party Infringement Claim that is subject to a Party’s indemnification obligations under ARTICLE 10, the applicable provisions of ARTICLE 10 shall control.

8.4.1.Duty to Notify of Competitive Infringement. During the Term, if either Party learns of an infringement, unauthorized use, misappropriation or threatened infringement by a Third Party with respect to any Licensed Technology by reason of the making, using, offering to sell, selling or importing of an ETB (or pharmaceutical product containing an ETB) directed against a Collaboration Target or Vertex Target in the Field in the Territory (a “Competitive Infringement”), such Party will promptly notify the other Party in writing and will provide such other Party with all available information regarding such Competitive Infringement.

8.4.2.Prior to Option Exercise. As between the Parties, for any Competitive Infringement with respect to a Collaboration Target that is not a Vertex Target, Company will have the sole right, but not the obligation, to institute, prosecute, and control a Proceeding to enforce any Licensed Technology against such Competitive Infringement by counsel of its own choice.

If Vertex fails to initiate such Proceeding within a period of [***] after written notice of such Competitive Infringement is first provided by a Party under Section 8.4.1, Company will have the right to initiate and control a Proceeding to enforce the Licensed Technology against such Competitive Infringement by counsel of its own choice at its own expense; provided that, if Vertex notifies Company during such [***] period that it is electing in good faith not to institute any Proceeding to enforce the Licensed Technology against such Competitive Infringement for strategic reasons intended to maintain the commercial value of the relevant Licensed Technology or any Licensed ETB or Licensed Product Covered thereby or relating thereto, Company will not have the right to initiate and control any Proceeding to enforce the Licensed Technology against such Competitive Infringement.

(a)If a Party initiates a Proceeding in accordance with this Section 8.4 , the other Party agrees to be joined as a party plaintiff where necessary and to give the first Party reasonable assistance and authority to file and prosecute the Proceeding. Subject to Section 8.4.5, the costs and expenses of each Party incurred pursuant to this Section 8.4.4(a) will be borne by the Party initiating such Proceeding.

(b)If one Party initiates a Proceeding in accordance with this Section 8.4 , the other Party may join such Proceeding as a party plaintiff where necessary for such other Party to seek lost profits with respect to such infringement.

With respect to any such permitted statement, the Parties shall coordinate their activities with respect to any submissions, filings or other activities in support thereof. (c) Notwithstanding the foregoing, the other Party’s consent under this Section 8.7 shall not be required to permit a Party to file with a court or agency a terminal disclaimer under 37 C.F.R. § 1.321(d) to overcome any obviousness-type double patenting in any patent application claiming a Licensed ETB, Licensed Product or one or more uses thereof.

8.8.Patent Term Extension . On a Licensed ETB-by-Licensed ETB basis, following the License Effective Date for such Licensed ETB, as between the Parties, Vertex will have the sole right and responsibility to obtain patent term extension in any country in the Territory under any statute or regulation equivalent or similar to 35 U.S.C. § 156, where applicable to the corresponding Licensed Products for such Licensed ETB. Vertex will determine the relevant Agreement Patents, if any, whose term will be extended (including, without limitation, by filing supplementary protection certificates and any other extensions that are now or in the future become available).

(a)the Research, Development, Manufacture, Commercialization, use or other exploitation of any Licensed ETB or Licensed Product by, on behalf of, or under the authority of, [***] or its Affiliates or Sublicensees or Subcontractors (other than by any [***] Indemnified Party), other than claims by one or more Third Parties that the practice of the ETB Platform in accordance with this Agreement infringes or misappropriates any issued Patent or other intellectual property rights owned or controlled by such Third Party(ies);

(b)the use by [***] at [***]’s direction in accordance with this Agreement of any Antibody to which [***] has obtained rights by directly contracting with a Third Party pursuant to Section 2.4;

(c)the material breach by [***] of any of its representations, warranties or covenants set forth in this Agreement; or

(d)the negligence or intentional misconduct of [***] or any [***]Indemnified Party;

except, in each case ((a)–(d)), to the extent such claims fall within the scope of [***]’s indemnification obligations under Section 10.1.2 (or would have had the Third Party claim been made against [***] under this Agreement) as to which Liability each Party will indemnify the other to the extent of their respective liability.

10.1.2.Indemnification by [***]. [***] will indemnify, defend and hold harmless [***], its Affiliates and its and its Affiliates’ employees, officers, directors and agents and their respective successors, heirs and assigns (each, a “[***] Indemnified Party”) from and against any Liability that the [***] Indemnified Party may incur or otherwise be required to pay to one or more Third Parties in connection with any Third Party suit, investigation, claim or demand resulting from or arising out of:

(a)any claim that the practice of the ETB Platform in accordance with this Agreement infringes or misappropriates any issued Patent or other intellectual property rights owned or controlled by any Third Party;

(b)[***]’s or any of its Affiliates’ or Subcontractors’ conduct of the Research Activities or the Follow-On Research, other than the use by [***] at [***]’s direction in accordance with this Agreement of any Antibody to which [***] has obtained rights by directly contracting with a Third Party pursuant to Section 2.4;

(c)the material breach by [***] of any of its representations, warranties or covenants set forth in this Agreement; or

(d)the negligence or intentional misconduct of [***] or any [***] Indemnified Party;

except, in each case ((a)–(d)), to the extent such claims fall within the scope of [***]’s indemnification obligations under Section 10.1.1 (or would have had the Third Party claim been made against [***] under this Agreement) as to which Liability each Party will indemnify the other to the extent of their respective liability.

10.1.3.Procedure. Each Party will notify the other Party in writing if it becomes aware of a claim for which such Party may seek indemnification hereunder. If any Proceeding (including any governmental investigation) is instituted against a Party with respect to which indemnity may be sought pursuant to Section 10.1.1 or 10.1.2, as applicable, such Party (the “Indemnified Party”) will give prompt written notice of the indemnity claim to the other Party (the “Indemnifying Party”) and provide the Indemnifying Party with a copy of any complaint, summons or other written notice that the Indemnified Party receives in connection with any such claim. An Indemnified Party’s failure to deliver such written notice will relieve the Indemnifying Party of liability to the Indemnified Party under Section 10.1.1 or 10.1.2, as applicable, only to the extent such delay is prejudicial to the Indemnifying Party’s ability to defend such claim and allow the Indemnifying Party to assume the defense of claim. Provided that the Indemnifying Party is not contesting the indemnity obligation, the Indemnified Party will permit the Indemnifying Party to control any litigation relating to such claim and the disposition of such claim by negotiated settlement or otherwise (subject to this Section 10.1) and any failure to contest such obligation prior to assuming control will be deemed to be an admission of the obligation to indemnify. The Indemnifying Party will act reasonably and in good faith with respect to all matters relating to such claim and will not settle or otherwise resolve such claim without the Indemnified Party’s prior written consent, which will not be unreasonably withheld, conditioned or delayed; provided that such consent will not be required with respect to any settlement involving only the payment of monetary awards for which the Indemnifying Party will be fully responsible. The Indemnified Party will cooperate with the Indemnifying Party in the Indemnifying Party’s defense of any claim for which indemnity is sought under this Agreement, at the Indemnifying Party’s cost and expense.

10.2.Insurance. Throughout the Term, Company and Vertex will respectively, at their own cost and expense, obtain and maintain the insurance coverage listed on Schedule 10.2 from insurance carriers licensed to do business under the laws of the country, state, commonwealth, province, or territory in which such Party’s obligations are provided, with insurers that carry a rating of at least an A- VII or better from A.M. Best. Each Party will furnish to the other Party evidence of such insurance upon request. Notwithstanding the foregoing, [***] may self-insure to the extent that it self-insures other activities similar to the activities under this Agreement.

10.3.Limitation of Consequential Damages. EXCEPT FOR (A) CLAIMS OF A THIRD PARTY THAT ARE SUBJECT TO INDEMNIFICATION UNDER THIS ARTICLE 10, (B) CLAIMS ARISING OUT OF A PARTY’S WILLFUL MISCONDUCT OR (C) A PARTY’S BREACH OF SECTION 5.6 OR ARTICLE 12 , NEITHER PARTY NOR ANY OF ITS AFFILIATES WILL BE LIABLE TO THE OTHER PARTY OR ITS AFFILIATES FOR ANY INCIDENTAL, CONSEQUENTIAL, SPECIAL, PUNITIVE OR OTHER INDIRECT DAMAGES OR LOST OR IMPUTED PROFITS OR ROYALTIES, LOST DATA OR COST OF PROCUREMENT OF SUBSTITUTE GOODS OR SERVICES, WHETHER LIABILITY IS ASSERTED IN CONTRACT, TORT (INCLUDING NEGLIGENCE AND STRICT PRODUCT LIABILITY), INDEMNITY OR CONTRIBUTION, AND IRRESPECTIVE OF WHETHER THAT PARTY OR ANY REPRESENTATIVE OF THAT PARTY HAS BEEN ADVISED OF, OR OTHERWISE MIGHT HAVE ANTICIPATED THE POSSIBILITY OF, ANY SUCH LOSS OR DAMAGE.

11.1.Term; Expiration. This Agreement is effective as of the Effective Date and, unless earlier terminated pursuant to the other provisions of this ARTICLE 11, will expire as follows (such period, the “Term ”):

(a)on a country-by-country and Licensed Product-by-Licensed Product basis, on the date of expiration of all payment obligations under this Agreement with respect to such Licensed Product in such country; and

(b)in its entirety (i) upon the expiration of all payment obligations under this Agreement with respect to all Licensed Products in all countries pursuant to Section 11.1(a) or (ii) upon the termination of this Agreement with respect to all Collaboration Programs pursuant to Section 11.2.1.

11.2.1.Automatic Termination of Collaboration Program. If, with respect to all Development Candidates arising under a Collaboration Program, Vertex does not exercise any Option under Section 4.1 on or prior to the applicable Option Deadline, then this Agreement shall automatically terminate with respect to such Collaboration Program, and, for clarity, the Collaboration Target for such Collaboration Program will automatically become a Terminated Target effective as of such Option Deadline with no further action by the Parties.

11.2.2.Vertex’s Termination for Convenience. Vertex may terminate this Agreement, either in its entirety or on a Collaboration Program-by-Collaboration Program or Licensed Product-by-Licensed Product basis, for convenience by providing written notice of its intent to terminate to Company, in which case, such termination will be effective [***] after Company’s receipt of such written notice.

(a)Vertex’s Right to Terminate. If Vertex believes that Company is in material breach of this Agreement, Vertex may deliver written notice of such material breach to Company. If the breach is curable, Company will have [***] following its receipt of such written notice to cure such breach. If Company fails to cure such breach within such [***] period or the breach is not subject to cure, subject to Section 11.2.4 , (i) Vertex may terminate this Agreement, in its entirety or with respect to the particular Collaboration Target or Licensed Product to which the breach relates, by providing written notice to Company, in which case, this Agreement will terminate in its entirety or with respect to such Collaboration Target or Licensed Product, as applicable, on the date on which Company receives such written notice or (ii) Vertex may elect to exercise the alternative remedy set forth in Section 11.4; provided, however, that if (A) the relevant breach is curable, but not reasonably curable within [***], and (B) Company is making a bona fide effort to cure such breach, Vertex’s right to terminate this Agreement or elect to exercise the alternative remedy set forth in Section 11.4 on account of such breach will be suspended for so long as Company is continuing to make such bona fide effort to cure such breach and if such breach is successfully cured, Vertex will no longer have the right to terminate this Agreement or elect to exercise the alternative remedy set forth in Section 11.4 on account of such breach.

(b)Company’s Right to Terminate. If Company believes that Vertex is in material breach of this Agreement, Company may deliver written notice of such material breach to Vertex. If the breach is curable, Vertex will have [***] following its receipt of such written notice to cure such breach. If Vertex fails to cure such breach within such [***] period or the breach is not subject to cure, subject to Section 11.2.4, Company may terminate this Agreement, solely with respect to the particular Collaboration Programs or Licensed Product to which the breach relates (or, if such breach relates to all Collaboration Targets or all Licensed Products, with respect to this Agreement in its entirety), by providing written notice to Vertex, in which case, this Agreement will terminate with respect to the applicable Collaboration Target or Licensed Product (or, if applicable, in its entirety) on the date on which Vertex receives such written notice; provided, however, that if (i) the relevant breach is curable, but not reasonably curable within [***], and (ii) Vertex is making a bona fide effort to cure such breach, Company’s right to terminate this Agreement on account of such breach will be suspended for so long as Vertex is continuing to make such bona fide effort to cure such breach and if such breach is successfully cured, Company will no longer have the right to terminate this Agreement on account of such breach.

11.2.4.Disputes Regarding Material Breach . Notwithstanding the foregoing, if the Breaching Party in Section 11.2.3 disputes in good faith the existence, materiality, or failure to cure of any breach, and provides written notice to the Non-Breaching Party of such dispute within the relevant cure period, the Non-Breaching Party will not have the right to terminate this Agreement in accordance with Section 11.2.3, or the right to exercise the alternative remedy provision of Section 11.4, as applicable, unless and until the relevant dispute has been resolved pursuant to Section 13.12. During the pendency of such dispute, the applicable cure period will be tolled, all the terms of this Agreement will remain in effect, and the Parties will continue to perform all of their respective obligations hereunder.

11.2.5.Termination for Insolvency. If, at any time during the Term, either Party makes an assignment for the benefit of creditors, appoints or suffers appointment of a receiver or trustee over all or substantially all of its property, files a petition under any bankruptcy or insolvency act or has any such petition filed against it that is not discharged within [***] after the filing thereof (each, an “Insolvency Event ”), the other Party may terminate this Agreement in its entirety by providing written notice of its intent to terminate this Agreement to such Party, in which case, this Agreement will terminate on the date on which such Party receives such written notice.

11.3.Termination by Company for Patent Challenge. Company may terminate the license granted to Vertex under this Agreement with respect to any applicable Licensed Patent upon [***]’ prior written notice to Vertex, if Vertex or any of its Affiliates or Sublicensees, directly or indirectly, individually or in association with any other person or entity, challenges the patentability, validity, enforceability, term or scope of such Licensed Patent anywhere in the world (“Patent Challenge”); provided that, if a Patent Challenge is brought by a Sublicensee, Company will not have the right to terminate the license granted to Vertex under this Agreement with respect to the applicable Licensed Patent if Vertex terminates its Sublicense agreement with such Sublicensee within [***] of receipt of Company’s notice of termination under this Section 11.3. The foregoing right to terminate the license granted to Vertex under this Agreement with respect to a Licensed Patent that is the subject of a Patent Challenge shall not apply with respect to any Patent Challenge that is made by Vertex or any of its Affiliates or Sublicensees in response to and defense of an assertion by Company of the relevant Licensed Patent. As used herein, a Patent Challenge includes: (a) filing an action under 28 U.S.C. §§ 2201-2202 seeking a declaration of invalidity or unenforceability of any Licensed Patent; (b) filing, or joining in, a request under 35 U.S.C. § 302 for reexamination of any claim of any Licensed Patent; (c) filing, or joining in, a petition under 35 U.S.C. § 311 to institute inter partes review of any Licensed Patent; (d) filing, or joining in, a petition under 35 U.S.C. § 321 to institute post-grant review of any Licensed Patent or any portion thereof; (e) filing or commencing any opposition, nullity, or similar proceeding challenging the validity of any Licensed Patent in any country or region; or (f) filing or commencing an action under any foreign statute or regulation that is equivalent or similar to clause (a), (b), (c), (d) or (e).

11.4.1.Alternative Remedy. If Company commits a material breach of Section 5.6 or 9.3(f) of this Agreement or commits a material breach of any other provision of this Agreement arising out of Company’s willful misconduct, and Vertex has the right to terminate this Agreement in accordance with Section 11.2.3 (including expiration of any applicable cure periods thereunder) (a “Company Breach Event”), in lieu of exercising such termination right, Vertex may elect the alternative remedy of this Section 11.4 by providing written notice of such election to Company before the end of such applicable cure period, in which case, [***]. Notwithstanding the foregoing to the contrary, if the material breach of this Agreement relates solely to one Target, the alternative remedy contained in this Section 11.4 shall only apply with respect to Licensed Product applicable to such Target.

11.4.2.Sole Remedy. Following a Company Breach Event, if Vertex [***], and elects to exercise its rights under Section 11.4.1 [***], then, without limiting any other remedies available to Vertex under Section 13.12.6, such election by Vertex shall be its sole and exclusive remedy for such Company Breach Event. For clarity, Vertex may elect, following a Company Breach Event, (a) [***] or (b) [***], Vertex may exercise any other remedies available to it under this Agreement or at law or in equity.

11.5.1.In General. If this Agreement expires or is terminated in its entirety or with respect to one or more Collaboration Programs or Licensed Products by a Party pursuant to Section 11.2, the following terms will apply to this Agreement, either in its entirety or with respect to the Collaboration Programs or Licensed Products that are the subject of such termination, as the case may be:

(b)termination or expiration of this Agreement for any reason will be without prejudice to any rights or financial compensation that will have accrued to the benefit of a Party prior to such expiration or termination. Such expiration or termination will not relieve a Party from obligations that are expressly indicated to survive the termination or expiration of this Agreement; and

(c)the following provisions of this Agreement will survive the expiration or termination of this Agreement: ARTICLE 1 (to the extent the definitions or schedules are used in other surviving provisions), Section 5.4, Section 5.7 (for the applicable time period set forth therein), the last sentence of Section 7.6.2 (solely in the event of expiration of this Agreement but not any early termination), Sections 7.9 through 7.12 (inclusive, solely to the extent applicable with respect to an accrued obligation otherwise contemplated by Section 11.5.1(b)), Section 8.1, Section 8.2.3, Section 8.5 (provided that all references therein to “that is not a Competitive Infringement” will be deemed deleted), Section 9.5, Section 10.1, Section 10.3, this Section 11.5, Sections 12.1 through 12.5 (inclusive and for the time period set forth therein), and ARTICLE 13 (but excluding Section 13.2 and Section 13.6)..

11.5.2.Effects of Termination. If this Agreement is terminated in its entirety or with respect to one or more Collaboration Programs or Licensed Products by a Party pursuant to Section 11.2, the following terms will apply, as applicable:

(a)if such termination is with respect to a Collaboration Program, then the Options granted to Vertex with respect to the Development Candidates arising under such Collaboration Program shall terminate;

(b)if such termination is with respect to a Licensed Product, except as set forth in Section 11.5.2(d), the Exclusive License with respect to such Licensed Product will terminate;

(c)any permitted Sublicense of Vertex with respect to a terminated Licensed Product will, at the Sublicensee’s option, survive such termination on the condition that the relevant Sublicensee is not in material breach of any of its obligations under such Sublicense and the Sublicensee’s breach was not the cause of Vertex’s breach hereunder. In order to effect this provision, at the request of the Sublicensee, Company will enter into a direct license with the Sublicensee on terms that are substantially the same terms as the applicable terms (including economic terms) of this Agreement; provided that (i) Company will not be required to undertake obligations in addition to those required by this Agreement and (ii) Company’s rights under such direct license will be consistent with its rights under this Agreement, taking into account the scope of the license granted under such direct license;

(d)subject to patient and other ethical considerations, Vertex shall wind-down any ongoing Clinical Trials for any terminated Licensed Product in accordance with Applicable Law, at Vertex’s cost; and

(e)if this Agreement is terminated by Vertex pursuant to Section 11.2.2 or by Company pursuant to Section 11.2.3 (as well as by Company pursuant to Section 11.3 if the applicable Patent Challenge is with respect to the last remaining Licensed Patent licensed by Company to Vertex under this Agreement), then notwithstanding the termination of the Exclusive License, to the extent Vertex, its Affiliates or Sublicensees can and do continue to Research, Develop, Manufacture or Commercialize any Licensed ETB or Licensed Product, Vertex shall remain obligated to pay amounts due to Company pursuant to Sections 7.5 and 7.6, and the terms of Sections 7.5, 7.6, 7.9, 7.10, 7.11 and 7.12 shall survive such termination; provided, however, that the Royalty Term as referred to in Section 7.6 shall mean, with respect to a Licensed Product in a country, the period commencing on the First Commercial Sale of such Licensed Product in such country and ending upon the latest of: (i) the expiration of the last Valid Claim of any Product Agreement Patent that Covers Agreement Know-How discovered, developed, invented or created by Company or its Affiliates or Third Parties acting on its behalf (whether solely or jointly with Vertex or its Affiliates or Third Parties acting on Vertex’s behalf) and that Covers such Licensed Product or the method of use or manufacture of such Licensed Product in such country; (ii) [***] after the First Commercial Sale of such Licensed Product in such country; or (iii) expiration of Regulatory Exclusivity, if any, in such country with respect to such Licensed Product.

12.1.Confidentiality. During the Term and for [***] thereafter, each Party (the “Receiving Party ”) receiving any Confidential Information of the other Party (the “Disclosing Party”) hereunder will: (a) keep the Disclosing Party’s Confidential Information confidential; (b) not publish, or allow to be published, and not otherwise disclose, or permit the disclosure of, the Disclosing Party’s Confidential Information to any Third Party; and (c) not use, or permit to be used, the Disclosing Party’s Confidential Information for any purpose, except, in each case, to the extent expressly permitted under this Agreement or otherwise agreed in writing.

12.2.Authorized Disclosure. Notwithstanding Section 12.1 , each Party may disclose the other Party’s Confidential Information to the extent such disclosure is reasonably necessary to:

(c)its actual or potential Sublicensees (in the case of Vertex and, in the case of Company, to its actual or potential sublicensees solely in connection with a sublicense of the rights granted to Company under Section 5.2.2) and actual or potential Subcontractors, in each case, in connection with the exercise of its rights and performance of its obligations under this Agreement; provided that such disclosure is covered by terms of confidentiality at least as restrictive as those set forth herein;

(d)its advisors (including financial advisors, attorneys and accountants), actual or potential acquirers, financing sources or investors and underwriters on a need-to-know basis; provided that such disclosure is covered by terms of confidentiality at least as restrictive as those set forth herein (which may include professional ethical obligations); or

(e)comply with Applicable Law (including to obtain and maintain Marketing Approvals for a Licensed Product).

If a Party deems it reasonably necessary to disclose Confidential Information belonging to the other Party pursuant to Sections 12.2(a), 12.2(b) or 12.2(e), then the Receiving Party will, to the extent possible, give reasonable advance notice of such disclosure to the Disclosing Party and take reasonable measures to ensure confidential treatment of such information.

Notwithstanding anything to the contrary herein, in no event may either Party, without the prior written consent of the other Party, disclose the other Party’s Confidential Information to any Third Party (including any of such Party’s Third Party investors, collaborators or licensees) engaged in the research, development, manufacture or commercialization of pharmaceutical products, other than to actual or potential Subcontractors or Sublicensees or to actual or potential acquirers or, in the case of Vertex, to actual or potential acquirers of Vertex’s program with respect to the Licensed ETBs or Licensed Products, provided that in the case of actual or potential Subcontractors or Sublicensees, such disclosures are made in accordance with Section 12.2(c), and in the case of actual or potential acquirers, such disclosures are made (i) in accordance with Section 12.2(d), (ii) only to the extent necessary to evaluate, negotiate and potentially consummate the acquisition and (iii) only after the applicable Party has reached agreement on a bona fide term sheet or letter of intent regarding the terms of such acquisition with the actual or potential acquirer.

Notwithstanding anything to the contrary in this Agreement, in no event will Company be permitted to disclose to any Third Party the identity of any Collaboration Target or Reserved Target, except as otherwise expressly provided in clause (e) of this Section 12.2 or to a Third Party gatekeeper under conditions of strict confidentiality pursuant to a mechanism substantially equivalent to that set forth in Section 2.3.2 and the Gatekeeper Agreement.

12.3.Expiration or Termination of this Agreement. Following the expiration or termination of this Agreement, if requested by the Disclosing Party, at the Receiving Party’s election, the Receiving Party will return or destroy, all data, files, records and other materials containing or comprising the Disclosing Party’s Confidential Information, except to the extent such Confidential Information is necessary or useful to conduct surviving obligations or exercise surviving rights. Notwithstanding the foregoing, (a) the Receiving Party will be permitted to retain one copy of such data, files, records and other materials for archival and legal compliance purposes and (b) the Receiving Party will not be required to delete or destroy any electronic back-up tapes or other electronic back-up files that have been created solely by the Receiving Party’s automatic or routine archiving and back-up procedures, to the extent created and retained in a manner consistent with its standard archiving and back-up procedures.

12.4.SEC Filings and Other Disclosures. Either Party may disclose the terms of this Agreement to the extent required to comply with Applicable Law, including the rules and regulations promulgated by the United States Securities and Exchange Commission or any equivalent governmental agency in any country in the Territory; provided that such Party will provide the other Party a reasonable opportunity to review such disclosure and reasonably consider the other Party’s comments regarding confidential treatment sought for such disclosure.

12.5.Residual Knowledge Exception. Notwithstanding any provision of this Agreement to the contrary, a Receiving Party may use any Residual Knowledge for any purpose; provided that, for clarity, this right to use Residual Knowledge does not represent a license to any Patents owned or Controlled by the Disclosing Party. Any use made by the Receiving Party of Residual Knowledge is on an “as is, where is” basis, with all faults and all representations and warranties disclaimed at the Receiving Party’s sole risk.

12.6.1.Announcements.

Notwithstanding the foregoing, subject to Section 12.6.2, Vertex may make scientific publications or public announcements concerning its Research, Development, Manufacture or Commercialization activities with respect to any Licensed ETB or Licensed Product under this Agreement without Company’s prior written approval; provided, however, that except as permitted under Section 12.2, Vertex will not disclose any of Company’s Confidential Information in any such publication or announcement without obtaining Company’s prior written consent to do so.

(a)Publications Prior to License Effective Date. During the Term prior to the License Effective Date with respect to a Development Candidate, neither Party will make any academic, scientific or medical publication or academic, scientific or medical public presentation related to such Development Candidate, the applicable Collaboration Target or any activities conducted pursuant to this Agreement with respect to such Collaboration Target, in each case, without the other Party’s prior written consent.

(b)Publications Following License Effective Date. During the Term following the License Effective Date with respect to a Development Candidate, Vertex will submit to Company for review any proposed academic, scientific or medical publication or academic, scientific or medical public presentation related to such Development Candidate, any corresponding Licensed ETB or Licensed Product, the applicable Vertex Target or any activities conducted pursuant to this Agreement with respect to such Vertex Target, no later than [***] before submission for publication or presentation (or [***] in advance in the case of an abstract). Company will review such publication or presentation for purposes of determining whether any portion of the proposed publication or presentation contains Company’s Confidential Information and will provide its comments with respect to such publications and presentations within [***] after its receipt of such written copy (or [***] in the case of an abstract). If requested by Company, Vertex will redact Company’s Confidential Information from any such proposed publication or presentation.

13.12.2.Mediation. If the Executive Officers are unable to agree on the resolution of any such Dispute within [***] (or such other period of time as mutually agreed by the Executive Officers) after such Dispute was first referred to them, then within [***] after the end of such [***] period or such other mutually-agreed period of time, either Party may serve notice to the other Party referring the matter to confidential mediation administered by the American Arbitration Association (“AAA ”) under its Mediation Procedures (subject to this Section 13.12.2) before resorting to arbitration pursuant to Section 13.12.3.

If the Parties are unable to agree on a mediator within [***] after service of the mediation notice, a mediator shall be appointed by the AAA. The mediation session shall last for at least [***] before any Party has the option to withdraw from the process. The Parties may agree to continue the mediation process beyond one day, until there is a settlement agreement, or one Party or the mediator states that there is no reason to continue. The Parties agree to have their respective principals participate in the mediation process, including being present throughout the mediation session(s). Any period of limitations that would otherwise expire between the reference of the Disputes to the Executive Officers of the Parties and the conclusion of the mediation shall be extended until [***] after the conclusion of mediation.

13.12.3.Arbitration. If the Dispute is not resolved through mediation within [***] after service of the mediation notice pursuant to Section 13.12.2, such Dispute shall be settled by binding arbitration in accordance with the Commercial Arbitration Rules of the AAA (the “Rules”). For clarity, the Parties may only resort to arbitration to resolve a Dispute after the Parties have escalated the Dispute to the Executive Officers pursuant to Section 13.12.1 and attempted to mediate the Dispute pursuant to Section 13.12.2. The Parties will follow the following procedures to resolve such Dispute under arbitration:

(a)Arbitrators. The number of arbitrators shall be three. The arbitrators shall be neutral and bound by The Code of Ethics for Arbitrators in Commercial Disputes. Each arbitrator shall have at least [***] of relevant experience in the pharmaceutical industry (and the field of pharmaceutical development, commercialization or any other relevant area, as applicable). Each Party shall select one arbitrator within [***] after the date the demand for arbitration (the “Demand for Arbitration”) is served upon the respondent, and the third, who will act as chairperson of the arbitral tribunal, shall be selected by the Party-selected arbitrators within [***] of their appointment, or, failing agreement by the Party-selected arbitrators, by the AAA in accordance with the Rules. If, at the time of the arbitration, the Parties agree in writing to submit the Dispute to a single arbitrator, said single arbitrator will (i) have at least [***] of relevant experience in the pharmaceutical industry (and the field of pharmaceutical development, commercialization or any other relevant area, as applicable) and (ii) be appointed by agreement of the Parties within [***] after the Demand for Arbitration, or, failing such agreement, by the AAA in accordance with the Rules. In no case shall any arbitrator have participated in a prior mediation involving either Party unless explicitly agreed to in writing by the Parties.

(b)Seat of arbitration; language . The seat, or legal place, of arbitration shall be Boston, MA, U.S.A. All arbitration proceedings will be conducted in the English language.

(c)Limited Discovery. Documentary discovery may be conducted at the discretion of the arbitrator(s), provided that any such discovery will (i) be limited to documents directly relating and material to the Dispute, (ii) be conducted pursuant to document discovery procedures as set forth under the laws of the International Bar Association Rules on the Taking of Evidence in International Arbitration, and (iii) be conducted subject to the schedule stipulated by the Parties, or in the absence of stipulation, the schedule ordered by the arbitrator(s). At the request of a Party, the arbitrator(s) may at their discretion order the deposition of witnesses. Depositions shall be limited to a maximum of [***] depositions per Party, each of a maximum of [***] duration, unless the arbitrator(s) otherwise determine. Notwithstanding any provision of this Section 13.12.3 to the contrary, all discovery must be completed within [***] after the appointment of the arbitrator(s).

(d)Awards and Fees. The arbitrator(s) may only issue awards of direct monetary damages and other damages to the extent set forth in Section 10.3 and will not under any circumstances have the authority or power to grant equitable relief or orders for specific performance. The allocation of expenses of the arbitration, including reasonable attorney’s fees, will be determined by the arbitrator(s), or, in the absence of such determination, each Party will pay its own expenses, including attorney’s fees.

(e)Rulings. All arbitration proceedings must be completed within [***] of the appointment of the chairperson or the single arbitrator. The Parties hereby agree that, subject to the provisions of this Section 13.12.3, the arbitrator(s) has authority to issue rulings and orders regarding all procedural and evidentiary matters that the arbitrator(s) deem reasonable and necessary with or without petition therefor by the Parties as well as the final award. The final award will be issued no more than [***] after the final submissions of the Parties, unless the Parties jointly request an extension or the arbitrator(s) determine(s), in a reasoned decision, that the interest of justice or the complexity of the case requires an extension. All rulings by the arbitrator(s) will be final and binding on the Parties. The arbitrator(s) shall issue a reasoned decision that accompanies the final award.

(f)Enforcement. The arbitration award shall be final and binding on the Parties, and the Parties undertake to carry out any arbitration award without delay. Judgment on the award may be entered in any court of competent jurisdiction.

(g)Confidentiality. All activities undertaken by the arbitrator(s) or the Parties pursuant to this Section 13.12.3 will be conducted subject to obligations of confidentiality no less restrictive than those set forth in ARTICLE 12. Further, the Parties acknowledge and agree that their respective conduct during the course of the arbitration, their respective statements and all information exchanged in connection with the arbitration, and the conduct of the arbitration and any information produced thereunder is Confidential Information under this Agreement and subject to the provisions of ARTICLE 12.

(h)Federal Arbitration Act. The Parties agree that this Agreement evidences a transaction involving interstate commerce. Notwithstanding the provision in Section 13.11 with respect to applicable substantive law, any arbitration conducted pursuant to the terms of this Agreement shall be governed by the Federal Arbitration Act (9 U.S.C. § 1 et. seq.).

13.12.4.Patent Disputes. Notwithstanding the foregoing in this Section 13.12, if a dispute arises between the Parties under this Agreement with respect to the interpretation, scope, validity, enforceability, applicability or term of any Patent, then such dispute shall not be resolved pursuant to Sections 13.12.1 through 13.12.3, but instead may be brought by either Party in the federal courts in the Commonwealth of Massachusetts.

13.12.5.Expert Determination. For any disagreement between the Parties regarding the calculation of “Net Sales” with respect to any Combination Product, such matter will be resolved by expert determination rather than pursuant to the foregoing procedures under this Section 13.12. The Parties hereby agree that such decision shall be conducted expeditiously by an independent expert selected unanimously by the Parties, which expert shall have relevant expertise and experience in the pharmaceutical industry, including with respect to the pricing of pharmaceutical and biologic products. If the Parties are unable to agree upon an expert within [***] after receipt of the notice of request for an expert determination, then, the AAA shall appoint such expert in accordance with the Rules. The expert, once appointed, shall have no ex parte communications with either Party concerning the expert determination or the underlying dispute. The Parties agree to cooperate fully in the expeditious conduct of such expert determination and to provide the expert with a written report including supporting documentation in connection with

such Party’s oral testimony if requested by the expert. At the conclusion of the arbitration hearings, each Party shall submit one (1) proposal to the expert. The expert shall accept only one (1) of the proposals submitted by the Parties (without making any changes to such proposal) and render such proposal as the expert’s final decision. Notwithstanding anything to the contrary in this Agreement, the expert shall not have the authority to render any decision other than selecting one (1) of the proposals submitted by a Party pursuant to this Section 13.12.5. The expert shall endeavor to resolve the dispute within [***] (but no later than [***]) after his or her appointment, taking into account the circumstances requiring an expeditious resolution of the matter in dispute. The expert’s decision shall be final and binding on the Parties. The costs of the expert determination shall be shared by the Parties, regardless of the outcome of the determination. All activities undertaken by the expert or the Parties pursuant to this Section 13.12.5 will be conducted subject to obligations of confidentiality no less restrictive than those set forth in ARTICLE 12. Further, the Parties acknowledge and agree that their respective conduct during the course of the expert proceedings, their respective proposals and all information exchanged in connection with the expert proceedings, and the conduct of such proceedings and any information produced thereunder is Confidential Information under this Agreement and subject to the provisions of ARTICLE 12.

13.12.6.Equitable Relief. Notwithstanding the foregoing in this Section 13.12, nothing contained in this Agreement will in any way limit or preclude a Party from, at any time, seeking or obtaining equitable relief hereunder, whether preliminary or permanent, including a temporary or permanent restraining order, preliminary or permanent injunction, specific performance or any other form of equitable relief, from any United States court of competent jurisdiction if necessary to protect the interests of such Party. Each Party agrees that its unauthorized release of the other Party’s Confidential Information or its breach of Section 5.6 of this Agreement will cause irreparable damage to other Party for which recovery of damages would be inadequate, and that such other Party will be entitled to obtain timely injunctive relief with respect to such breach, without the need to show irreparable harm or the inadequacy of monetary damages as a remedy, and without the requirement of having to post bond or other security, as well as any further relief that may be granted by a court of competent jurisdiction.

13.13.Entire Agreement. This Agreement constitutes and contains the complete, final and exclusive understanding and agreement of the Parties and cancels and supersedes all prior negotiations, correspondence, understandings and agreements, whether oral or written, between the Parties respecting the subject matter hereof, including the CDA, which is hereby superseded and replaced in its entirety as of the Effective Date. All information shared by the Parties pursuant to the CDA will be Confidential Information under this Agreement from and after the Effective Date, and the use and disclosure thereof will be governed by ARTICLE 12.

13.14.Independent Contractors. Both Parties are independent contractors under this Agreement. Nothing contained herein will be deemed to create an employment, agency, joint venture or partnership relationship between the Parties or any of their agents or employees, or any other legal arrangement that would impose liability upon one Party for the act or failure to act of the other Party. Neither Party will have any express or implied power to enter into any contracts or commitments or to incur any liabilities in the name of, or on behalf of, the other Party, or to bind the other Party in any respect whatsoever.

13.15.Interpretation. Except where the context expressly requires otherwise, (a) the use of any gender herein will be deemed to encompass references to either or both genders, and the use of the singular will be deemed to include the plural (and vice versa), (b) the words “include,” “includes” and “including” will be deemed to be followed by the phrase “without limitation,” (c) the word “will” will be construed to have the same meaning and effect as the word “shall,” (d) any definition of or reference to any agreement, instrument or other document herein will be construed as referring to such agreement, instrument or other document as from time to time amended, supplemented or otherwise modified (subject to any restrictions on such amendments, supplements or modifications set forth herein), (e) any reference herein to any Person will be construed to include the Person’s successors and assigns, (f) the words “herein,” “hereof” and “hereunder,” and words of similar import, will be construed to refer to this Agreement in its entirety and not to any particular provision hereof, (g) all references herein to Sections or Schedules will be construed to refer to Sections or Schedules of this Agreement, and references to this Agreement include all Schedules hereto, (h) provisions that require that a Party, the Parties or any committee hereunder “agree,” “consent” or “approve” or the like will require that such agreement, consent or approval be specific and in writing, whether by written agreement, letter, approved minutes or otherwise (but excluding e-mail and instant messaging), (i) references to any specific law, rule or regulation, or article, section or other division thereof, will be deemed to include the then-current amendments thereto or any replacement or successor law, rule or regulation thereof, (j) any action or occurrence deemed to be effective as of a particular date will be deemed to be effective as of 11:59 PM ET on such date and (k) the term “or” will be interpreted in the inclusive sense commonly associated with the term “and/or.”

13.16.No Third Party Rights or Obligations. No provision of this Agreement will be deemed or construed in any way to result in the creation of any rights or obligations in any Person not a Party to this Agreement.

13.17.Further Actions. Each Party agrees to execute, acknowledge and deliver such further instruments, and to do all such other acts, as may be necessary or appropriate in order to carry out the purposes and intent of this Agreement.

13.18.Counterparts. This Agreement may be executed in two counterparts, each of which will be an original and both of which will constitute together the same document. Counterparts may be signed and delivered by digital transmission (e.g., .pdf), each of which will be binding when received by the applicable Party.

IN WITNESS WHEREOF, the Parties have caused this Agreement to be executed by their representatives thereunto duly authorized as of the Effective Date.
